That’s according to Sky Sports Spanish football expert GuillemBalague, who has suggested the Germany international could be on the move at the end of the season because he’s unhappy in Madrid. United, Balague thinks, could be one of a number of teams interested.

“I do believe he wants to leave Real,” said Balague (h/t Colin Harvey of the Daily Star). “It will be a fight for anyone to get him, but he would be ideal for Manchester United. There will be a fight for him this summer.”

According to AS (h/t Will Giles of Metro.co.uk), Kroos has already had a lot of offers to leave Los Blancos, with Arsenal being another team mentioned. Before he signed for Real in the summer of 2014, United were strongly linked with the player. However, Adam Crafton of MailOnline reported that manager Louis van Gaal pulled the plug on a deal.

Although Kroos may be enduring a difficult season at the Bernabeu, he’s a class player and would be a major coup for most sides in Europe. Here is a look at why:

In terms of pure passing ability, there are few players in world football who can measure up to Kroos. The German can put raking balls on a sixpence from flank to flank, making him an extremely useful player to have in the squad.

His technical skill, intelligence and winning mentality are other positive traits.

So even though the 26-year-old has been shy of his best in 2015-16, he’s still a potent weapon, as OptaJose noted here:

What Kroos does need is support in the middle of the park. For all his quality, playing at the base ofthe midfield with little energy around him—as he does for Los Blancos—isn’t ideal to get the best of his qualities. Defensively, he's neither the best nor the most dynamic.

A player such as Morgan Schneiderlin would be a perfect foil for the German, and if United could secure a deal, that’s a pairing plenty at Old Trafford would love to see.

However, if Kroos does become available at the end of the season, the Red Devils won’t be the only football superpower in for his signature.

MattiaPerin 'Ready' for Big Move

The agent of Genoa goalkeeper MattiaPerin has insisted the youngster is ready to make the step up to an elite outfit, although he won’t move until a position at a top club becomes available.

Manchester United and Liverpool have both been linked with the stopper this season, but according to his representative, Matteo Roggi, there’s no rush to move him on any time soon, per Radio Kiss Kiss (h/t talkSPORT):

Unless the wheel of international goalkeepers starts spinning, nobody is going to move.

As soon as somebody moves, a domino effect begins. He's ready for a leap of quality into a top club, but he could also take an intermediate leap and play in the Europa League.

We're ready for the change, but we're peaceful about it. We won't leave just for the sake of leaving, as he's already playing in a great team.

For a 23-year-old, Perrin displays a maturity and assurance that only usually come with experience when operating in his position. Here is a look at what he’s capable of:

Admiring glances from United would be understandable. Granted, they have one of the world’s best on their books in David De Gea, but they came close to losing him to Real Madrid last summer before a deal collapsed.

Balague recently told Sky Sports he has a £30 million buyout clause in De Gea's contract and that Los Blancos will return for him at the end of the campaign.

There are a lot of similarities between Perin and De Gea when he joined United in 2011. He’s immensely talented but still has plenty to learn. So if United's star stopper were to depart in the summer, triggering the “wheel of international goalkeepers” to which Roggi referred, it’d be little surprise to see the Italian on the club’s radar.
